The dead period for college football recruiting ends Friday, and while about two-thirds of the top high school prospects already have signed their letter of intents, top players remain.

Two of the best in the Bay Area are offensive lineman Blake McDonald of San Ramon Valley and St. Francis defensive tackle Tyler Manoa.

McDonald has his two finalists — Cal and Nebraska. He said Thursday that he will make a decision after taking his official visit to Nebraska on the final weekend in January.

Manoa was supposed to take an official visit to Oregon this weekend, but that has been pushed back to later this month because of basketball obligations. Manoa’s final three are Oregon, UCLA and Utah, although there are rumblings that USC might try to sneak into the picture.

Junior Fehoko, a 6-4, 235-pound defensive end and Manoa’s teammate at St. Francis, is mulling offers from Cal, San Jose State and Hawaii, Lancers coach Greg Calcagno said.

Kairee Robinson, the De La Salle running back/defensive back, also has set an official visit to San Jose State on Jan. 26.

The late signing period begins Feb. 7.

McDonald wouldn’t say which school he is leaning toward, but in addition to his Nebraska visit, the Cornhusker coaches have an in-home visit next week.

“I’ll probably just official Nebraska,” said McDonald, adding that he has been to Cal many times. But the Bears’ coaches have not scheduled an in-home visit, McDonald said.

Should the 6-5, 295-pound McDonald choose Cal, it would be a major coup for coach Justin Wilcox, who already has signatures from three of the top four offensive linemen in Northern California, according to the 247Sports.com recruiting site. They are Granite Bay four-star tackle Will Craig, Clayton Valley’s Brandon Mello and Bishop O’Dowd’s Miles Owens. McDonald would make it a clean sweep.
